DGPS Beacon System | 15

3 DGPS Beacon System

As Maritime Safety Administrations, Navy, and Coast Guard Organizations realize the

limitations of standard GPS positioning, many have begun installing DGPS Beacon

Stations. While an understanding of this system is not necessary for operating receivers

with internal beacon receivers, you may want to read on to have a better understanding

of how your receiver is capable of achieving the high levels of accuracy made possible by

this network of transmitters.

The DGPS Beacon System is comprised of three segments: the reference station,

Integrity Monitor (IM) equipment located at the beacon site, and the Navigator

equipment located on board the user’s boat or vehicle. The DGPS beacon system design

is illustrated below.

Because of the limited range of the beacon transmitters, typically 150 to 400 km, the

corrections generated by the reference station are always valid for users who can

receive the correction signals and maintain a 5 meter or better accuracy figure.
